How Much SOL Do You Need to Launch on pump.fun?

The honest answer is "whatever you want to buy, plus a little". Creating a pump.fun coin is cheap. What costs SOL is the dev buy and the other wallets buying in the same bundle, and you choose those numbers.

So the useful question is not "how much does pump.fun charge" but "how do I add it all up so no wallet comes up short". Here is the formula, then three worked budgets.

#The formula

Every bundled launch has the same five parts:

Then there is one item you pay only the first time you launch from a DevBundler account: the address lookup table, about 0.005 SOL. It gets reused for every later launch.

#What the small amounts pay for

Wallet overhead. A wallet that buys a token needs a token account to hold it. On Solana, accounts pay rent, and a token account costs about 0.002 SOL. The rest of the 0.003 covers transaction fees. The rent is not gone forever: close the token account later, after you have sold, and it comes back. Solana rent and token accounts explained has the details.

Coin accounts. When the coin is created, someone pays for the mint, the bonding curve account and the metadata. That is the dev wallet, and it is why the dev wallet needs about 0.03 SOL more than the others.

Jito tip. On mainnet, the launch goes out as one Jito bundle. The tip is what gets a block builder to include it. Too low and the bundle can sit unpicked until it expires. We suggest starting at 0.005 SOL and raising it when the network is congested. Tip levels move, so treat any number as a starting point.

Platform fee. DevBundler charges a percentage fee on the SOL spent in launch buys. The exact amount is shown in the confirmation dialog before you send, and larger launches can get a lower rate. pump.fun also has its own trading fees, which change from time to time, so check their current figures rather than trusting an old blog post, including this one.

#Three worked budgets

These use the overhead numbers above. They leave out the platform fee because it depends on your rate, so add it on top using the figure the app shows you.

Add about 0.005 SOL to any of these if it is your first launch and the lookup table does not exist yet.

The default bundle column is DevBundler's suggested setup: 1 SOL for the dev and 0.5 SOL for each buyer. In a real quote on a fresh mainnet curve, those four wallets end up holding about 8.18% of supply together, with the curve about 10% sold. The full bundle uses all 10 buyer slots, which the free plan does not allow, so check your plan's wallet limit before you budget for it.

Notice how small the overhead column is next to the buys. Even with 11 wallets, the extras come to well under a tenth of a SOL. If you are trying to save SOL, the place to look is the buy sizes, not the fees.

#Budget by percentage instead

If you care more about how much of the supply your wallets hold than about the SOL, work backwards. DevBundler can take buys as a percentage of supply and work out the SOL for you. A real quote:

• Dev at 3% of supply: 0.8711 SOL
• Buyer 1 at 2%: 0.6092 SOL
• Buyer 2 at 2%: 0.6335 SOL
• Buyer 3 at 2%: 0.6592 SOL

That is about 2.77 SOL of buys for 9% of supply, then the same overhead as before. Each buyer pays a little more than the last for the same 2%, because every buy moves the price up the bonding curve. How to choose your dev buy size goes into what percentage makes sense for the dev wallet.

#What if I do not have much SOL?

You can launch with a small dev buy and no buyer wallets at all. It costs little, but it also means you hold very little of your own coin, and anyone can buy in the blocks after the create.

A smaller bundle is often the better compromise: a modest dev buy and two or three buyers at small amounts. The overhead per wallet stays the same, so very tiny buys spread across many wallets are not efficient. Five wallets buying 0.05 SOL each pay the same 0.003 SOL overhead as five wallets buying 1 SOL each.

#How DevBundler shows the total

You do not have to do this math by hand. On the launch page, a live table lists each wallet's balance, its buy, its estimated share of supply and the SOL it needs. Any wallet that is short shows in red and blocks the launch button. The confirmation dialog then shows the totals, the fee and the tip in one place before anything is sent.

The fastest way to see your own numbers is to set up the launch on devnet, where the SOL is free, and read the table. Then go through the pump.fun launch checklist before switching to mainnet.
